Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 79820, here are decompositions:

3 + 79817 = 79820
7 + 79813 = 79820
19 + 79801 = 79820
43 + 79777 = 79820
127 + 79693 = 79820
151 + 79669 = 79820
163 + 79657 = 79820
193 + 79627 = 79820

Showing the first eight; more decompositions exist.
